NAND flash memory system based on the Harvard buffer architecture for multimedia applications
Pages 6287 - 6302
Abstract
The main purpose of this research is to design a new memory architecture for NAND flash memory to provide XIP (execute in place) for code execution as well as overcome the biggest bottleneck for data execution. NOR flash for multimedia application is particularly well suited for code storage and execute-in-place (XIP) applications, which requires high-speed random access. While NAND flash provides high density and low cost data storage, it is not applicable to XIP applications due to the page access and long access latency. To overcome these limitations, NAND flash can be exploited as code memory for XIP by using SDRAM/SRAM buffer. In order to design the code memory, we proposed a NAND flash with a dual instruction buffer. Furthermore, another enhancement was proposed for the overall system performance by applying a data buffer system to the existing NAND flash memory to reduce the number of write and erase operations; otherwise which could be the biggest bottleneck in a flash memory system. In conclusion, the proposed NAND flash buffer system based on Harvard architecture is operated as main memory as well as the lowest storage device for mobile multimedia system. According to our simulation results, write and erase operations are approximately 60 % and 68 % less than other unified buffer systems, respectively, with two times more space. In addition, the average memory access time is improved by approximately 75 % compared with other unified buffer systems.
